LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 366,396, dated July 12,1887.

Application filed November 29, 1886. Serial No. 220,182.

To aZZ whom it may concern:

Be it known that I, ELLTAH PRESCOTT HUssEY, of Ellis, in the county ofEllis and State of Kansas, have invented a new and Improved Lubricator,of which the following is a full, clear, and exact description.

This invention relates to the construction of a novel form of lubricatordesigned for use in connection with the crank-pin of a locomotiveengine,the object of the invention being to provide for the regular deliveryot'small quantities of oil to the crank-pin, and to prevent thedischarge of oil except at times when the engine is in motion.

- To the end named the invention consists of an oil-cup formed with aninternal upwardlyextending tube the top of which constitutesavalve-seat-,a valve formed with a downwardlyextending spindle that fitswithin the bore of said tube, and with an upwardly-extending stem thatfits within the bore of aplug that is adj ustably connected to the coverof the cup, all as will be hereinafter more fully described, andspecifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar figures of reference indicatecorresponding parts in both the views.

Figure 1 is a side view of my improved form of lubrieator, and Fig. 2 isa central vertical sectional view of the same.

In the drawings, represents the oil-cup, within which there is arrangedan upwardlyextending tube, 11, formed with a flaring top or mouth, 12.The cap or cover of the cup 10 is shown at 13, and is formed with adownwardl y extending projection, 14, that is threaded to engage with aninternal thread formed at the mouth of the cup. This cover or cap 13 iscentrally apertured, and in the aperture so formed there is fitted athreaded plug, 15, in the lower end of which there is a bore or chamber,2, the central aperture of the cap being internally threaded,in orderthat the cap may be engaged by the plug.

The valve arranged in connection with the oil-cup is shown at 20, andthis valve is formed with a downwardlyextending spindle, 21, which fitsloosely within the bore of the'tube 11, and projects downward beyond thelower projection, 22, of the cup 10, while the stem of the valve, whichis shown at 23, projects upward and fits within the bore 2 of the plug15.

This plug 15 is provided with a jam-nut, I

(No model.)

2,5,which, when turned down hard against the top of the cup 13, acts tobind or clamp the plug to such position as may be required. The cup isapplied to the bearing of the crankpin, the projection 22 being insertedand secured within a socket provided for its reception, the parts beingheld together by a setscrcw; or, if desired, the projection 22 might bethreaded to engage with a corresponding thread. formed in the socket.After the device has been applied as described the valve will be causedto rise and fall by the mo tion of the engine, which motion will alsoagitate the oil contained within the cup, so that it will strike uponthe upper face of the valve and drip downward drop by drop, to bedelivered by the spindle 21 directly to the crank-pin; but when theengine is at rest the valve will be tightly closed upon its seat, and itwill be impossible for any of the oil to escape. The supply of oildelivered by the spindle of the valve may be regulated by adjusting theplug 15 so as to provide for more or less play of the valve, as will bereadily appreciated by those skilled in the art.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a lubricator, the combination, with anoil-cup provided with an internal upwardlyextending tube having aflaring top or mouth and with an apertured cap, of a valve fitting inthe flaring top'or mouth of the tube, and provided with a spindleprojecting into the said tube and with a stem projecting into the'apertured cap, substantially as herein shown and described.

2. In a lubricator, the combination, with an oil-cup formed with aninternal upwardly-ex tending tube the top of which constitutes avalve-seat, of a valve formed with a spindle that fits within the tubeand projecting slightly beyond the extreme lower end of the cup and withan upwardly-extending stem, a detachable cover, a plug that is threadedto engage with the central threaded aperture formed in the cover, saidplug being formed with a central bore and adapted to receive avalve-stem, and a jam-nut fitted upon the plug, substantially asdescribed.
